G.V. Bogatyryova, Ch.V. Felde, P.V. Polyanskii Comparative analysis of techniques for diagnostics of phase singularities.//Proc. of SPIE. - 2008. - Vol. 7008

The comparative analysis of several techniques for diagnostics of phase singularities in the optical vortex beams and fields is performed. Both advantages and disadvantages in the implementation and applications of different techniques are dis- cussed.
